    Study Notes

    Signs & Symptoms of Pulmonary Disease

    • Dyspnea (most common): breathing discomfort
      • Orthopnea: dyspnea that occurs when an individual lays flat; often seen in heart failure
    • Cough (most common): protective reflex to clear airways
    • Abnormal sputum: changes in amount, color, and consistency (always culture!)
      • Hemoptysis: coughing up of blood or bloody secretions
      • Empyema: pus in the pleural space of the lungs
    • Abnormal breathing patterns: changes in breathing effort
      • Kussmaul respirations: deep, rapid, and labored breathing (seen in diabetic ketoacidosis)
      • Cheyne-Stokes respirations: alternating periods of deep and shallow breathing with apnea between; common in individuals actively dying

    Hypoventilation & Hyperventilation

    • Hypoventilation: Inadequate alveolar ventilation; often seen in drug overdose
    • Hyperventilation: Alveolar ventilation exceeds metabolic demands; too much CO2 being expelled
    • Cyanosis: Bluish discoloration of skin & mucous membranes due to desaturated hemoglobin; not always present in a deoxygenated state
    • Clubbing: Bulbous enlargement of digit ends; associated with chronic hypoxemia (e.g., bronchiectasis, cystic fibrosis, pulmonary fibrosis)

    Restrictive Lung Diseases

    • Difficulty getting air into the lungs
    • Decreased compliance: more effort to expand the lungs

    Bronchiolitis

    • Diffuse, inflammatory obstruction of small airways; common in children

    Pulmonary Fibrosis

    • Excessive fibrous tissue in the lung; can be idiopathic or caused by scar tissue after lung disease, autoimmune disorders, or irradiation
    • Marked loss of compliance

    Inhalation Disorders

    • Exposure to toxic substances
    • Dust particles, asbestos, and coal are common causes (AKA Coal Miners Disease)
    • Hypersensitivity pneumonitis

    Acute Lung Injury (ALI) & Acute Respiratory Distress Syndrome (ARDS)

    • Acute Lung Inflammation and Diffuse Alveolocapillary Injury
    • Diagnosed by history, exam, blood gases, and CXR.
    • Three phases:
      • Exudative (within 72 hours): Damage to endothelial cells causes capillary membrane permeability; fluids leak into interstitium and alveoli; lower compliance, decreased tidal volume, and hypercapnia; acute respiratory failure.
      • Proliferative (within 4-21 days): Diffusion barrier forms, resulting in progressive hypoxemia.
      • Fibrotic (within 14-21 days): Remodeling and fibrosis of lung tissue; potential for long-term respiratory compromise.

    ARDS Manifestations

    • Dyspnea
    • Hypoxemia
    • Hyperventilation/Hypoventilation
    • Poor tissue perfusion
    • Respiratory failure, poor cardiac output, hypotension, death

    ARDS Supportive Therapy

    • Focused on maintaining adequate oxygenation and ventilation while preventing infection; often requires mechanical ventilation
    • GOAL IS OXYGENATION!

    ARDS Positioning

    • Frequent position changes with the "good lung down"
    • Head of bed elevated 30 degrees
    • Prone positioning improves gas exchange

    ARDS Causes

    • Aspiration, inhalation injury, sepsis, embolism, pneumonia, trauma

    Obstructive Lung Diseases

    • Impaired ventilation and oxygenation
    • Airway obstruction worse with expiration
    • Common signs and symptoms: dyspnea and wheezing

    Common Obstructive Disorders

    • Asthma
    • COPD
    • Emphysema
    • Chronic bronchitis

    Asthma

    • Chronic airway inflammation; antigen initiates innate and adaptive immune responses in sensitized individuals
    • Very common in children
    • Manifestations:
      • Wheezing on exhalation (high-pitched sound in upper lobes)
      • SOB
      • Chest constriction
      • Tachycardia/tachypnea
      • Excessive accessory muscle use

    Asthma Treatment

    • Avoidance of allergens and irritants
    • Low-dose corticosteroids and short-acting beta-agonist inhalers
    • Anti-inflammatory medications for severe cases
    • Immunotherapy

    Chronic Obstructive Pulmonary Disease (COPD)

    • Persistent airflow limitation; progressive; most common lung disease worldwide; 4th leading cause of death globally
    • Combination of chronic emphysema and bronchitis
    • Risk factors:
      • Tobacco smoke
      • Occupational dusts/chemicals
      • Air pollution
      • Factors affecting lung growth during fetal development and childhood (e.g., low birth weight, respiratory tract infections)

    Chronic Bronchitis

    • Hypersecretion of mucus and chronic productive cough lasting for at least 3 months of the year for at least 2 consecutive years
    • Inspired irritants increase mucus production and the size and number of mucous glands
    • Mucus produced is thick
    • Cilia is gone or ineffective, unable to clear mucus

    Chronic Bronchitis Treatment

    • Prevention is key: Stop smoking to halt disease progression
    • Bronchodilators, mucolytics, antioxidants, and anti-inflammatory drugs
    • Physical therapy (deep breathing and postural drainage)
    • Acute exacerbations: antibiotics and corticosteroids; may require mechanical ventilation

    Chronic Bronchitis Manifestations

    • Productive cough
    • Dyspnea
    • Wheezing
    • Prolonged expiration
    • Cyanosis
    • Chronic hypoventilation
    • Polycythemia
    • Cor pulmonale

    Emphysema

    • Abnormal and permanent enlargement of gas-exchange airways with destruction of alveolar walls (no fibrosis)
    • Primary emphysema (1%-3% of cases) is linked to an inherited deficiency of alpha 1-antitrypsin
    • Loss of elastic recoil causes air trapping, leading to hyperexpansion of the chest (barrel chest) and increased work of breathing
    • Individuals often purse their lips to help get air in

    Emphysema Manifestations

    • Dyspnea
    • Wheezing
    • Barrel chest
    • Prolonged expiration

    Tuberculosis

    • Infection caused by Mycobacterium tuberculosis, usually affecting the lungs
    • Highly contagious and airborne; can result in latent TB infection
    • Bacteria may lodge in lymph, initiating an immune response
    • Diagnosed via TB skin test
    • Abscesses can destroy lymph tissue and cause cavitation when they empty into bronchi
    • Treated with antibiotics

    Pulmonary Embolism

    • Thrombus: stationary clot
    • Emboli: traveling clot through the blood
    • Thromboemboli: dislodged thrombus traveling
    • Occlusion of a part of the pulmonary vascular bed by a thrombus, embolus, tissue fragment, lipids, or air bubble
    • Commonly arise from deep veins in the legs (ambulation is important after surgery!)
    • Virchow triad: venous stasis, hypercoagulability, and injuries to endothelial cells

    Pulmonary Artery Hypertension (PAH)

    • Mean pulmonary artery pressure 5-10 mmHg above normal or above 20 mmHg
    • Respiratory system diseases and hypoxemia are most common causes
    • May not be detected until severe
    • Manifestations:
      • Fatigue
      • Chest discomfort
      • Tachypnea
      • Dyspnea (particularly with exercise)
      • Peripheral edema, JVD, accentuation of the pulmonary component of the second heart sound

    Cor Pulmonale

    • Pulmonary heart disease; right ventricular enlargement
    • Develops as PAH exerts chronic pressure overload in the right ventricle, causing hypertrophy and ultimately failure
    • Goal of treatment is to reduce workload of the right ventricle by lowering pulmonary artery pressure

    Malignancies of the Respiratory Tract

    • Lung (bronchogenic): most common cause is cigarette smoking
      • Heavy smokers have a 20-times greater risk of developing lung cancer than non-smokers
      • Smoking linked to cancers of the larynx, oral cavity, esophagus, and urinary bladder
      • Environmental and occupational risk factors can also contribute
      • Clinical manifestations listed in Table 29.3
    • Non-small cell is most common: squamous cell carcinoma, adenocarcinoma, large cell carcinoma
    • Small cell: from neuroendocrine tissue
